My friend is moving house and she's concerned about how her landlord with take the severe cat scratchings on the wooden window frame. Is there any product - like a putty or something - that can make the scratches seem not so bad?
If depends if it is painted or not - your local DIY shop can sell you a filler suitable for filling wood that can be sanded down and painted over and your landlord would be none the wiser - especially if it was painted white.
Mahogany frames would be a different kettle of fish.
